Embodiment 2

[0143] The surgical instrument in the second embodiment of the present invention is basically the same as the surgical instrument in the first embodiment, the same parts will not be described, and only the differences will be described below.

[0144] Please refer to Figure 14 and Figure 15 ,in Figure 14 It is a top view of the wire transmission structure provided by Embodiment 2 of the present invention, Figure 15 It is a perspective view of the wire transmission structure provided by Embodiment 2 of the present invention.

[0145] In the second embodiment, the arrangement of the guide wheels corresponding to the traction body on the guide seat is different from that in the first embodiment. Specifically, such as Figure 14 to Figure 15 As shown, the first guide seat 17 is provided with the third guide wheel 161, the first guide wheel 171 and the sixth guide wheel 173; the second guide seat 16 is provided with the fifth guide wheel 163, the second guide wheel 175 and ...

Embodiment 3

[0148] The surgical instrument in the third embodiment of the present invention is basically the same as the surgical instrument in the first embodiment, the same parts will not be described, and only the differences will be described below.

[0149] Please refer to Figure 16 , which is a schematic diagram of the transmission plane of the wire transmission structure provided by Embodiment 3 of the present invention.

[0150] In the third embodiment, the arrangement of the end drive shafts corresponding to the traction body is different from that in the first embodiment. Specifically, such as Figure 16 As shown, the third end drive shaft 14 of the third transmission module is farther away from the end of the instrument than the second end drive shaft 13 of the second transmission module. Further, the first end drive shaft 12 of the first transmission module and the third end drive shaft 14 of the third transmission module are arranged symmetrically with respect to the secon...

Abstract

The invention provides a surgical robot and a surgical instrument. The surgical instrument comprises a wire transmission structure and an instrument tail end, wherein the wire transmission structure comprises a base and n transmission modules, each transmission module comprises at least one tail end driving shaft, two traction bodies and two guide wheels, each guide wheel comprises a wire groove for accommodating the corresponding traction body, and the wire groove comprises a wire groove rotating surface, an entry tangency point and a departure tangency point; and the included angles formed by the traction bodies defined by the tail end driving shafts and the entry tangency points and the rotating surfaces of the wire grooves are 0-0.2 degree, and the projections of all the traction bodies at the departure tangency points on the proximal end are ordered in the circumferential arrangement sequence of corresponding through holes. Due to the arrangement, the wire transmission structure of the surgical instrument can reduce or eliminate friction resistance between the wire grooves and the traction bodies through fewer guide wheels, the traction bodies cannot be mutually overlapped andscratched, the transmission efficiency of the wire transmission structure of the surgical instrument is improved, and the service life of the surgical instrument is prolonged.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a surgical robot and surgical instruments. Background technique [0002] In recent years, with the application and development of robot-related technologies, especially the development of computing technology, the role of medical surgical robots in clinical practice has attracted more and more attention. Among them, the minimally invasive surgical robot system can reduce the physical labor of doctors during the operation through interventional therapy, and at the same time achieve the purpose of precise surgery, so that patients have less trauma, less blood loss, less postoperative infection, and faster postoperative recovery. The design of the surgical instruments used in the surgical robot directly determines the success or failure of the minimally invasive surgical robot system, and the performance of surgical instruments is a key factor affecting the performance ...
